An unseasonably cold air mass that originated in Siberia poured across the Middle Atlantic States on the 18th. The combination of strong northwest winds (winds gusted to around 30 mph during the latter half of the morning) and unseasonably cold air produced wind chill factors that fell between zero and 10 degrees below zero during the morning and early afternoon of the 18th. Actual low temperatures during the morning of the 18th ranged from the single numbers in northwestern New Jersey to the teens elsewhere.  Many municipalities declared a code blue to help get homeless people off the streets and into shelters. The city of Camden (Camden County) opened the doors to its Malandra Hall Community Center as a shelter. As the core of the arctic air mass moved east, winds diminished toward evening on the 18th.
